Crome and Uberdata are just programs that are used to modify Honda fuel and ignition maps. You will need the hardware plus some way to get the information from the computer to the chip.

You can download Uberdata and Crome from http://forum.pgmfi.org. All the hardware you need to get those functional is on www.moates.net.

Give Crome a try. I prefer it over Hondata any day.
